Firewall blocks some files in file upload contact form

Hello,

I use WPforms Basic in order to allow customers to upload files in a contact form.
Wordfence blocks some file uploads when i enable the Firewall in Wordfence. But when i disable the firewall it works flawlessly.

Files that are impossible to upload with firewall enabled are: .eps and .ai etc.
